The basics of how to conduct participant observation are not taught in law schools. This is striking because this methodology has become a common feature of qualitative research and could be very useful in sociolegal research. For those interested in studying ‘law in practice’ instead of ‘law in the books’, qualitative research methods like participant observation are inevitable. However, participant observation is, at best, secondary in the literature on qualitative research in the sociolegal discipline, while there is no guidance on how to conduct this technique whatsoever.Therefore, this article is written with two audiences in mind: It should serve as a useful reference and guide for those who teach qualitative research methods in legal education and who are looking to enhance their knowledge and skills concerning participant observation; it is also meant to serve as a basic primer for the beginning sociolegal researcher who is about to become a participating observer for the first time.
